Motorola first announced its intention to migrate its mobile "smart" phones to embedded Linux in 2003. The first such phone to reach the market was the A760 in the fourth quarter of that year. Today there are a dozen or so models (differing product numbers in different markets and minor hardware variations lead to different counts), but there are still no significant ecosystems for third-party applications or developers. Is Motorola's switch to Linux a hit for the company but a miss for end users?
